The perimeter will also be scaled down by half if the original triangle if it were scaled down by half.
<h3>What is the perimeter of a triangle?</h3>The total length of a triangle's boundary is referred to as its perimeter. It is the total of the triangle's three sides. A triangle's perimeter will be equal to a+b+c if its three sides are a, b, and c.
The sides of the original triangle are:
x+3, 2x+4, 3x-1
The perimeter of the triangle will be
If it were scaled down by half then new sides will be
So, the perimeter of the new triangle will be
This is half of the original triangle's perimeter. Therefore, the perimeter of the new triangle is half of the perimeter of the original triangle.

The word "of" is the same thing as a multiplication sign!
So instead see it this way:
53% × 470
To solve this, you can use the cross product method :
=
(470 × 63) ÷ 100 = ?
29 610 ÷ 100 = ?
296.1 = ?
53% of 470 is 296.1
There you go! I really hope this helped, if there's anything just let me know! :)
